摘　　要：为研究线控转向系统的关键技术及其面临的挑战,概述了汽车转向系统的发展轨迹,分析了线控转向系统较传统转向系统的优势,研究了国内外汽车线控转向系统的研发及应用现状。通过分析路感反馈控制、转向执行控制、冗余设计3个线控转向关键技术,总结了线控转向系统对自动驾驶技术的意义及复杂工况下技术挑战和低成本量产挑战。未来线控转向系统应作为线控底盘的一部分,通过整车底盘垂向控制、纵向控制、横向控制进行融合协调控制。To explore the key technologies and challenges associated with Steer-By-Wire(SBW),this paper offers a comprehensive review of the automotive steering system’s evolution,analyzes the advantages of SBW over traditional steering system,and examines the current research and application landscape across the globe.This paper analyzes 3 key SBW technologies including road feel feedback strategy,steering execution strategy as well as redundant strategy,and summarizes the significance of SBW for autonomous driving technology,technical challenges under complex working conditions and the low-cost challenge of mass production.Looking ahead,SBW is poised to become an integral part of the wire-controlled chassis,where it will enable holistic control of the vehicle’s vertical,longitudinal,and lateral movements.
